Q103 / 160 · JIPMER 2014 · Physics

An observer is approaching with velocity $v$ towards a light source. If the velocity of light is $c$, then velocity of light with respect to observer will be

A
$c-v$
B
$C$
Correct answer
C
$c+v$
D
$\sqrt{1-v^2 / c^2}$

Solution

Observer and light are moving towards each other, so relative velocity is $c+v$.

Hence, the correct answer is option: 'C'.
